| 摘 要： | 最近,我们摸索出的硝酸刻蚀法制备有SERS(Surface Enhanced Raman Scattering,表面增强拉曼散射)活性的银表面,有良好的热稳定性,且费用低廉,预期在研究金属表面反应、催化和金属-聚合物界面结构等方面可发挥作用。在展示了这一新方法具有极高的表面增强因子后,本文介绍用该法研究吸附质的自集合(self-assembly)和表面取向结果。

| Abstract: | A simple chemical method for preparing SERS active surfaces was developed by etching silver foils in concentrated HNO_3 solutions. The enhancement factors were calculated to be 10~6 as compared with solution spectra. The technique was applied to investigate the self-assembly of benzyl disulfide and adsorption orientation of thiophenol on silver surfaces. The results show that the HNO_3 roughened silver foil seems to be a more routinely preparable substrate system for SERS study. |
